Compared to other general thread machining methods, rotary milling has the following advantages: 1.High processing efficiency, which can be more than 10 times higher than the traditional processing efficiency; 2.Due to the molding process, the product is shaped by one knife, and the eccentric cutting does not need to retreat, with high precision; 3.The rotary milling transformed by the lathe does not change the structure of the lathe, the spiral lift angle is adjustable, easy to install; save the cost of investing in special equipment; 4.Surface roughness up to RaO. 8 microns and 2 levels of machining accuracy; 5.Slow axial feed of the lathe, easy to operate, the professional skills of workers can be reduced; |
